YAMAHAYZF-600R 2003 - 2004

　　In 2003, the Japanese motorcycle manufacturer released the Yamaha YZF-600R, a bike that carried on the amazing blend of sport-natural behavior and comfort but also was a street-oriented almost identical version of the R6 supersport beast, which differed from each other by the one-piece two-up seat and less edgy design.

　　With enhanced ergonomics, the YZF-600R was a great choice for a sporty commuter and even for long hauls with its optional luggage system, and thanks to its responsive suspension and tall windscreen, the bike was transformable into an enjoyable sport-touring machine.

　　As for power, the 2003 Yamaha YZF-600R featured a 599cc engine with durable, lightweight, short-skirt, forged pistons for reduced weight and increased throttle response that provided strong power for both aggressive sport riding and everyday commuting.

　　The four-stroke four-cylinder liquid-cooled engine delivered an output power of 100 hp with a peak at 11,500 rpm and 66 Nm (49 lb-ft) of torque available at 9,500 rpm. All the power was converted into speed by a six-speed manual transmission linked to the rear wheel by a chain drive that pushed the bike to a top speed of 247 kph (153 mph).

　　As for braking performance, the bike packed two 300 mm discs squeezed by a couple of four-piston calipers on the front wheel and a 245 mm disc with a two-piston caliper on the rear.
